摘　　要：根据CO_2制冷压缩机的运行特点,设计了一套适用于跨临界循环的压缩机性能检测装置,该装置适用于制冷量为14 kW^70 kW的冷冻冷藏及热泵系统用CO_2压缩机的测试,试验方法为制冷剂气体流量计法和跨临界气体冷却器法;在此基础上开展了CO_2制冷压缩机的性能测试,结果表明,该压缩机的主侧制冷量、辅侧制冷量及主辅侧平均值的测量结果重复性偏差均在±1%以内。According to the operation features, a performance test equipment for transcritical CO2 Refrigeration compressors is designed. The equipment is suitable for performance test of the refrigeration and heat pump CO2 compressors which cooling capacity within 14 kW-70 kW, and the testing methods are gas Refrigerant flowmeter method and transcritical gas-cooler method. A CO2 Refrigeration compressor model is tested on this equipment and the results indicate that the repeatability deviations of primary cooling capacity, auxiliary cooling capacity and average cooling capacity are within ±1%.
